Application filed January 29. 1907- Serial No. 35 f78fi3i with SoarkingMechanism for Explosion- Engines, of which the -following is a full,clear; and ez isct description.

The present invention relates to a contact maker oi iiistrihnter for thesparking devices of explosion motors especially applicable tohiglitension ins-gnetosi 'lhis contact maker or distributor ischoi'nctcrized essentially by gear or planet pinioiis running upon thein terior of o fixed insulated ring carrying contests connectecl hyC(HKlLLCtOl'S with the ter' niinals upon the cylinders and driven hypinion mounted upon the axis of thenmg neto which hitter wheel isconnected to the extniimity or the secondary who, in such manner thstthe secondary current passes through the movable wheels when the lettercome into contact with the contests of the ring. This contact makerpossesses numerous advent-ages, hereinafter ic' erreii to, end

oil which the most important is thatgit can he applied directly upon theof the iogneto without the necessity ior reducing gearing.

in the accompanying drawings: Figure 1 isaliieiid elevation of theconstruction mount ei'l upon s magneto Fig. 2 is e corresponding sideview. Fig 3 is a horizontal section tslren on the line A i i oi Fig.Fig. i is it view illustrot' c nioi'liiticstion.

n; ieii'ing to the cravings, the contact maker or distributor comprisespinions a l) the miles a, t of which inoi'inteol upon e or yoke cpivotslly mounted upon the extremity of the shaft. The pinions a I) runupon the fixed ringd of insuleting insterial carrying conductingcontacts e e e e connected to termnels f f f to which are connected thesparking wires leading to the cylinders. These pinions gear, u on thether side, with the pinion g rotating with the armature of theiii-cgneto.

The section in Fig". 3 shows on exoinple of the method of mounting thecontact .mcker The rod Fr, iorniiiig the connected to the Wire endtrevupon the magneto 4 short of the errnsiture is cross the insulatingpieces 3 moontedinthe .plate Z which is cepehle oi rotelting upon hellbearings m. The pinion g is mounted upon the extremity of the shaft 77,.

A plate n incloses the contact maker While permitting of easy inspection.

The action of the apparatus isas follows: The pinion g rotates with thearmature of the magneto and drives the pinions o b causing the letter totrov'el around the fixed ring d.

The pinions s end. l) make one revolution mechanism of the around theaxle I to several revolutions of the pinion g according to thediilerence in th development or xtent of the toothed sur feces of thepinions a in the example given, which relates to it four cylinder motorthe pinions a and t melts one revolution in every four of the pinion iJhen one orthe other of the pinions aend I? is in contact with theconducting cont-cots e e e c it places the secondary circuit inelectricsl connection with the sparking plug of the correspondingcylinder. T he result is that at half turn of the pinions s end I; soinoes to out the four cylinders in contact with the secondary circuit;during this half turn, the pinion two revolutions. As the magneto givestwo sparks per revolution four sparks have been produced. t it 'Wlllthus be seen that during a halt turn of the two pinions a o, it is thepinion c which makes contest end .(hii'ing the chewing half turn it isthe pinion b. I

in the modification shown sthig. 4c, the pinions o and Z2 are free andere sits in piece hy an overlapping plots 0.

The invention is assumed to he applied to a motor having four cylindershot it will he evident thst it may he applied to motors having anynumber of cylinders.

instead-of two pinions 0 b, three might be arranged and the fourterminals f f f distributed over it third of the circumference of thering; the soeed of the movehle her or yoke will he still further reducedont ss tor as this is concerned one is limited by the space necessaryforplecing the contscts with the necessary intervals between thorns Without greetly 'ccreesing the dimensions of thc ring entl c tact meter The;contect maker or distributor retire sented es s oplierl to e hiehtension magneto; this epperetus'is ocrticu srly suitshletothisspplicetion but it may he eq iieilytvell op and b and the ring and thearmature hove mecle y held v plied 'to low tension magnetosindependently or in combination with any appropriate construction.

The, arrangements hereinbefore described are only given by Way ofexample.

The forms, dimensions and arrangements ma be varied according tocircumstances Wit out departing from the principle of the invention.

Claims:

1 The combination with the rotary and stationary elements of a magnetogenerator, of a stationary insulating ring having an internal rack andcontacts, a rotary gear connected to said rotary element to be driventhereby, a planet gear of conducting material meshing With said rack androtary gear, and adapted in its planetary movement to make electricalconnection with said contacts, and a Wire in which current is induced bythe relative movement of the rotary and stationary elements, said Wirebeing electrically connected to said rotary gear, substantially asdescribed.
